摘    要:该文研究了水曲柳(FraxinusmandshuricaRupr.)发生I型断裂时裂纹尖端的应力场应力强度因子的情况.借助美国大型通用有限元分析软件NASTRAN计算出裂纹尖端附近的应力,并通过GRAFTOOL软件对数据进行后期处理,画出裂纹尖端附近的应力强度因子分布图.

关 键 词:木材断裂力学,水曲柳,木材裂纹,木材断裂,应力,有限元,应力强度因子

Abstract:The paper is concentrated on the stress strength factors of mode fracture at crack tip of Fraxinus mandshurica Rupr.Firstly, by NASTRAN software of the United States MSC Company the data of stresses are figured out, and then, by GRAFTOOL software dealing with the data, the distribution diagram of stress strength factors at crack tip of Fraxinus mandshurica Rupr. are drawn.
Keywords:wood fracture mechanics  Fraxinus mandshurica Rupr    wood crack  wood fracture  stress  finite element  stress strength factor
